Y No. 865,945.

To mhmn it may concern.

lle it known that we, Joux Rousn'rs unl .Latins E. Buss. citizens of theUnited States. residing at Faust, in the county of Franklin and State ofNew `:'ork. have in vented new and useful Improvements' in Ties. ofwhich the following is a specification.

The invention relates to an improvement in ties,'and particularly to ametallic tie constructed to'provide a firm support for railroad mils. Y

e The main object of the present invention is the pro-` duction of nmetallic tie constructed to afford a firm support for railroad mils, andto provide a means for securing the rail in position on the tie, the tiestructure including a rail cushioning means arranged to absorb thevibrations of the rail incident to the travel thereon and preventtransmiidori of such vibration tothe tie.

The invention will be described in the following 7 specification,reference being had particularly-to the accompanying drawings, inwhich:-

Figure l is a plan view illustrating the use of our improved tie, Fig. 2isa longitudinal section through the tie on line 2-2 of Fig. l,illustrating the preferred form of cushioning means, Fig. 3 isasimilarview illustratinga modified form of cushioning means, Fig. 4 isa plan viewof the tie removed. y Fig. 5'is a transverse section on line5-50f1fig. 2.

Referring particularly to the drawings, our improved tie comprises arectangular body 1 formed in the relatively upper surface withacentrallydisposed depression 2. Beyond thedepression the tie isapproximatelysolid to provide heads El to receive the rails, the end walk of thedepression being arranged within the mil r11-cking portion of the tie.The depression 2 is of mmc-what less extent transversely and verticallythan the simile:- dimensions of the tie,- whereby the tie is in effectof holow construction between the heads.

Each head 3 is formed on 'the relatively upper surface with a milreceiving recess 4. one-half of the recess being formed by undeicnttingthe maierial of the head, Where-A by to provide a lip 5 oveily'ing aportion of the recess and spiced imm the bottom wall thereof. Betweenthe relatively inner-ends of the lips 5 of the tie, the thickluw of thebody l is reduced by a distnnce approxinuitcly equal to the thickness ofthe lip. so that the inner lmlf of thc rect-m4 is fully open. the innerboundary thcuuf being defined by a unzqmnltively slight shoullder 6.tcntizdly of thc length of the recess l the heads 2t an* zich formedwith n vertically extemling'oinning 7 adapted to contain Ille vilmttionabsorber. as will puse-nth' uppczir.

The iunci' surface of the lip 5 is shaped to conform to tlurllrvntnrc.Jamil buse S, :ind the dcpll of the 11u-css 4- Ilm! i.; tile distancefrom ilnel itfncr sul'l'me of thc lip Patented sept. 1o, 1907. i

5 to the bottom .wall of the recess is slightly in excess of thethickness of the rail flange 8. A tie plate 9 is arranged to cover thesurface of the tie between the recesses 4, the respective ends of midplate overlying the open portion of the recess and sha pcd. as at 10, toconform to the contour of the base flange of the mil. The tie plate istro-extensive in width with the width of the tie, thereby covering thedepression 2 therein. The tie plate is secured in place by means ofbolts 11, shaped at their lower ends to provide hooks 12, adapted toengage appropriately formed openings 13 in the side walls of thedepression 2, the upper ends of thi` bolts' being threaded and passedthrough registering openings 14 in the tie'plate 9, said bolts beingsecured beyondthe tie plate by nuts 15'to cooperate with the threadedends thereof.

The openings 7 in the recesses 4 are adapted to contain a means forabsorbing to a considerable degree the vibration of the rails, whereby,to avoid transmission of this vibration to the tie with the consequentinjurious effect upon the road As shownin Fig. 2 the predrical body ofresilient material, as rubber 16, snugly fitting in the openings 7 inthe tie with the upper end of the body projecting above the bottom wallof the rece-.w 4. In Fig. 3 the Ashock absorber is shown in the form of'a coil spring 17, seated in the openings 7 and norm-.illy projectingabove the bottom of the recesses 4.

The rails are secured in position on the tie in the manner illustratedin Fig. 2, the outer projection of the base flange of the rail beinginserted beneath the lip 5; the inner portion of said flange beingsecured beneath the appropriately formed end of the tie plate l). T hevlatter is secured in position by the use of the bolts 1]thercby securingthe rails to the tie in a trimmer to provith` a firm support thereforwithout interfering with the independent movement of the rail essentialto its expansion and contraction under changes oi the temp-culture.

The rail rests directly upon thc shock absorbingr bt n'ly, hencematerially reducing the tntnsmisdou ot' thc vibration of 'the rail tothe tie, and thcrcby avoiding; 'lo :i considerable extent a vibration ofthc tic with conscqucnt danxging influence upon th rondbcd. 'lbc uudersurface of flic tie is for-mcd with a wnon'l lot' greater longitudinalextent than that of thc dcpi'ifiou 2, fming in effect a recess fortlwwn-ptiou ci material forming the roadbed, u'lxicli'in plumufill Icndto prih vent indqiondcnt longitudinal tnovcnlcnl of thc fio.'

In tbe use ofthe tic :isa support forlhc nwclingcnib ofmilroad mils, n'cprcfcr to combine with thv tic' rcinforcing plates l!) dcsigucd to beapplied to opposinsidcs of thc u'cb lmrtions of tbc t'cs}mti\'c rails nnilbc wcui'cd to tlnmil und to nich other by bolts '.UfV llni'erred formof shock absorber is in the forni of n cylinlun plates i9 Lire adaptedto rest sqimrely upon the lips 5 :uid the ilange engaging purlion ui theie plate 9, thereby materially minion-ing the rail securing means 0i thetie, While at the sume time securing the meeting ende nf lli-. milfsl inmanner to insure their alimentent. under uml-nl cenditions 0i travel. A

The tie uumlr-timed :Le described provides a simrrfle and Convenen:suppnrt for milrlmd rails, in which the vihmlinn rn' the rniis will beabsorbed to a material ex- Lent` The .zils may he released al any timeby removing the tie plate fi, as will be obvious. i

While preferring the use of duplicate reinforcing plates 19. it isobvinus that only one such plate may be nfwl it' desired. Furthermore,the tie plate 9 may be farmed in une or more sections with independentsecuring means. The depression 2 maj1 be used to contain a tie ballast,if desired.
